Data Action Notifications

Notifications can be displayed as confirmations after any data manipulation operations.

Let’s implement a code business rule to display a notification after every Update, Insert, and Delete action.

Enable shared business rules. Generate the web app.

Start the Project Designer. On the toolbar, press Develop to open the project in Visual Studio.

In the Solution Explorer, double-click on ~\App_Code\Rules\SharedBusinessRules.cs(vb).

Replace the existing code with the following:


using System;
using System.Data;
using System.Collections.Generic;
using System.Linq;
using MyCompany.Data;

namespace MyCompany.Rules
    public partial class SharedBusinessRules : MyCompany.Data.BusinessRules
        protected override void AfterSqlAction(ActionArgs args, ActionResult result)
            base.AfterSqlAction(args, result);
            if (result.Errors.Count == 0 && args.CommandName == "Update" ||
                args.CommandName == "Insert" || args.CommandName == "Delete")
                Result.ShowAlert("The action {0} has been completed.", args.CommandName);

Visual Basic:

Imports MyCompany.Data
Imports System
Imports System.Collections.Generic
Imports System.Data
Imports System.Linq

Namespace MyCompany.Rules

    Partial Public Class SharedBusinessRules
        Inherits MyCompany.Data.BusinessRules

        Protected Overrides Sub AfterSqlAction(args As ActionArgs, result As ActionResult)
            If (result.Errors.Count = 0 And Arguments.CommandName = "Update" Or
                Arguments.CommandName = "Insert" Or Arguments.CommandName = "Delete") Then
                result.ShowAlert("The action {0} has been completed.", Arguments.CommandName)
            End If
        End Sub

    End Class
End Namespace

Save the file. Press Ctrl+F5 to run the web application from Visual Studio.

Navigate to any page, edit a record, and save. A popup window will open, displaying a notification.
